SUBIVIERGED PUMP.

SPECIFICATION forming part of Letters Patent No. 263,406, dated August 29, 1882.

Application filed September 1, 1881.

To all inkom it may concern:

Be it known that I, LOUIS HERBERT, of Hicksville, in the county of Sacramento and. State of California, have invented certain new and useful Improvemen tsi n Submerged Pumps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying' drawings.

My invention relates toimprovementsin submerged double-acting pumps.

It consists in certain novel construction and combinations of parts by which I am enabled to provide a cheap, simple, effective, and easilyoperated hand-pump, as will be more fully set forth and described hereinafter.

The accompanyingdrawings herein referred to show,in Figure 1, an elevation of my improved pump and the manner ot' securing it in position for operation over the well or shaft, the pump-cylinder with its plunger and valves being in section. Fig. 2 shows the air-chamber and upper structure of the pump and the cut-off valve or device for changing the course ot' the discharged strcam,theparts beingshown in section. Fig. 3 is an enlarged section ofthe pump cylinder or chamber containing the plunger and valves. Figs. 4 and 5 are cross-sections through the lines .r x yy, Fig. 3. Fig. 6 is a detailof the construction of the cut-oli de fleeting-valve. Fig. 7 is an end view taken from the lefthand side of Fig. 1.

A is the tube that forms the body of the pump. It is composed of sections or lengths of pipe properly coupled together, with the pumpcylinder secured to the lower end, while its upper end terminates in an air-chamber. This air-chamber B is an enlargement of the first section of tube A, and by means of a tiange, d, near the lower end, this part of the structure, which is above the supporting-platform X, is secured and held in position. The end ot' the tube-section below this iiange receives the remaining sections, A' A2, so that the entire pump-body is suspended from and supported by this flangein a firm and stable manner.

O is the cylinder or pumping-chamber,which is immersed in the body of water below, and takes the water at each stroke of the plunger into the inlet at the bottom and through the (No model.)

side apertures or perforations provided at the top ofthe cylinder. Each of these inlets is controlled by inwardly-acting valves acting against the valve-seats c f, and the water,when 5 5 By referring to Fig. 3 of the drawings it will be 6o seen that this chamber is composed of three sections, C C G2, bolted together by means of the iianges, provided one upon the other, and forming a cylindrical compartmen t for the plunger or piston D and a passage or water way,g,

leading therefrom and connecting with the tube or body of the pump. The section c contains the valves and plunger, and has also the compartment or water-way divided from it by the partition h, but connected with it through the 7o outlet-apertures i t, the upper one ot' which is closed by the clapper-valve s. This valve s works on a pintle, m', that passes through the bodyoft-hechamberfromtheoutside,anditcontrois both the passage in the water-way when the plunger is moving upwardV and the apen' ture i at the time the plunger is moving downward, as will be understood from the sectional View, Fig. 3.

The seat for the upwardly-acting valve G is 8o formed by the plate c, secured on the bottom of the chamber (J, while the upper valve, G', acting downward, has a seat against the ring j', which is placed on the end of the section O before the next one, C, is fixed in place. These parts therefore are easily detachable and can be readily removed for cleaning and repairing. The middle section, O', has openings or perforations k, through which the water enters, and

is drawn into the cylinder O through the valve 9o G at each downward movement ot' the plunger, and it has also the closed passage g, which connects with and forms a continuation ofthe water-way g in the cylinder C. Upon the top end ot' this section is also formed a stuftingg5 box, l, for the plunger-rod T, and over the passage or water way g is an upwardly-acting valve, n, which is raised by the pressure of the water beneath it. This valve is seen in Figs. 3 and 4. It is placed in the passage roo above the water-way for the purpose of obtaining a continuous flow of water as soon as the pump is started, as without it the Water must be raised every time from the pump-cylinder up into the tube and chamber before a iow can be obtained ofthe discharge. In locations where the pump would be exposed during cold weather this valve n can be dispensed with and the water allowed to run back into the cylinder to prevent freezing; but in such case, while the pump will operate to raise the water j ust as well, the flow will not take place until the plunger is worked long enough to till the tube. The third section, G2, is fixed over and incloses the stuffing-box l and the valve a, and isjoined tothe end of the lowest section, A, of the upright tube or body ofthe pump. The water-space of this section C2 is gradually contracted as it rises above the valve n, and it terminates in a cylindrical end, o, to connect with the tube A. This construction gives a simple compact form of plunger-chamber, and providesfor ready access to the working parts.

The plunger-rod T is carried up through the center of the tube A A and out at the top of the air-chamber through a stuffing-box, P, at the top. Guides q q are fixed in the sections of tubes A at intervals to hold the rod in proper vertical position. To connect the rod with the operating-lever R, I tix upon the end ofthe rod a yoke, a, with internal slots, a a', along each side, to receive and guide two rollers,]"f, that are carried by the end ot' the lever. The hand-lever It is supported by the frame U, which is bolted to lugs t t provided for the purpose on the top of the air-chamber, and this frame is formed of the two uprights and the cross-head c, which forms a guide for the rod T above the yoke, so that the plungerrod is caused to work in vertical position. These parts cfj change the oscillation ofthe hand-lever into avertical reciprocating motion ofthe plungerrod. This gives a regular even stroke, and is a strong and simple attachment for connecting the rod and operating-lever together. The frame U 'v gives a strong and substantial support for the lever, and serves also as a guide for the plunger-rod, as before stated.

The discharge from the pump is through the spout W, hich leads from the side ofthe body A just below the chamber or enlargement. At this point, also, I provide a simple eifective means for directing the discharging stream and turning it into a conductingpipe, b, to be led ott' to a distance when required. This consists ofthe short cylinders', extending upward from and around an opening in the upper side ofthe spout, and connected at the end with a pipe, b, leading off to any distant part ot' discharge. Within this cylinder is a sliding tubular valve, u, open at the top and at one side, which is capable ot' a vertical movement into and out of the space within the spout, so that by pushing this tube down into the spout W the outlet from the spout will be shut oft', and the water will then flow into the opening y and risc up through the tube fw and into the pipe above. The end'of this tube 1c, when pushed down to cut off the stream, is received into a seat, formed in the bottom of the space within this spout, so that no water can pass beneath it, and a packing, rv', fixed around the end of the tube to produce a tight joint at this point. To move this cut-off and detlecting valve, I provide two vertical slots in the sides of the cylinder diametrically opposite to each other, and through these slots two short arms or handles, V V, fixed to the sides ofthe tube w, project in such manner that by grasping one of the handles in each hand the valve can be readily moved up or down as required. This construction is clearly shown in Figs. 1 and 6.

Having thus described my invention, what I cla-im, and desire to secure by Letters Patent, 1s-
